This'invention relates to an arrangement for controlling temperatures in a massage device and has particular reference to the type of massage device comprising a hollow container into which certain temperature producing reagents are introduced to initiate the temperature reaction whether it be heating or cooling.

An object of the invention is to provide a simple, compact device which can be readily manipulate for massage purposes and in which the desired temperature eiects'can quickly, easily and accurately be produced, maintained and controlled throughout the 1l use of the device whilel massaging.

Further and more specific objects, features, and advantages will more clearl}7 a pear from the detailed description given elow taken in connection lwith the accompanying I drawings which form part of the specification, which illustrate oneembodiment of the invention, and in which y Fig. 1 is an elevation of the assembled massage device;

Fig. 2 is a cent-ral vertical section taken through the device shown in Fig. 1;.

Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2; and

Fig. 4 is a horizontal section taken on the line 4--4 of Fig. 2.

The form of the invention which I now consider to be the preferred one, comprises a hollow container 10, preferably of sm'ooth polished metal,having a narrow upper neck 11 interiorly threaded at 12 to receive the outer threads 13 on a stopper sleeve 14. At the top this sleeve is open but at the bottom it is provided with a wall 15 having perforations 16. At the top the sleeve 14 has an outwardly extending flange 17 fitting tightly in a similarly shaped groove 1.8 in the lower end of a handle portion 19. This handle portion is hollow and provided on its lower end with a dependent flange 20 fitting snugly between the sleeve 14 and an upstanding ange 21 on the upper end of the neck 11 of the con tainer 10. The handle 19 is preferably of heat insulating material, such as Wood or hard rubber, and its above described connection with the container permits the handle to be grasped firmly in the hand while the container or massage body portion 10 is moved around in contact with the surface being treated.

Against the lower face of the perforated' plate l5 is disposed a valve washer 22, preferably' of rubber, and supported on a flanged plate 23 of metal mounted around the shaft or rod 24 and held thereon by means of nuts 25 and 26. Against the upper face of the wall 15 bears a compression spring 27, the upper end of which bears against a plate 28 fastened to the rod 24 near the top thereof.` This plate has peripheral apertures therein as 29.

The upper end of the handle 19 is open and interiorly threaded at 30 to receive a threaded cap sleeve 31 having a flange 32 resting on the top of the handle 19. This flange 32 has a central-hole in which lies a button 33 connected to the upper end ofthe shafaor rod 24. An outwardly extending flange 34 is formed on the lower end of the button 33 and lies beneath the under face of the ange 32 to keep the button from projecting too far out of the handle. Screwed into the lower end of the sleeve 31 is an annular ring 34a to act as a stop member and limit the depression of the but-ton 33.

A liquid, such as water, 35, is placed in the hollow handle and is prevented fromdropping into the container chamber while the valve 22 is'olosed. Bub when the button 33 is depressed to uncover the perforations 16, the liquid in desired quantities is permitted to drop into the container 10 and react with a salt 36 placed in the bottom thereof. This salt is preferably in loose granulated form and is one which will cause a temperature reaction when mixed with a solvent thereof, such as Water. In a preferred instance I employ ammonium nitrate and sometimes add a small quantity of potassium nitrate thereto. I may also add a small portion of gelatine to the mixture since I have found that it will lslow un the temperature reaction. By providinar the valve to control the admission of the solvent, a small quantity thereof can first be admitted to start the temperature reaction, and then as it commences to die out a further quantity is admitted to maintain the average intensity of the reaction. Thus the reaction can be controlled throughout entire use of a given quantity of salt and the temperature controlled to a finer degree than s before. The salt above mentioned is one which will produce a cooling eiect when mixed with water, but it is to be understood that I may use other salts as desired.

While I have described my improvement 10 in detail and with respect to a preferred form thereof, I do not desire to be limited to such details or form since many changes and modiications may be made and the invention embodied in other forms without departing from 15 the spirit and scope of the invention in its broader aspects. Hence I desire to cover al1 modifications and forms coming within the language or scope of any one or more of the appended claims.

2 What I claim as new and desire to secure by Letters Patent, is:.

1. A massage device comprising a massage container adapted to contain a salt, a hollow handle connected thereto, and adapted 2f to contain a liquid medium, a valve between the handle and the container, a stem connected to the valve and extending u throu h the hollow handle, means for ho ding t e valve on its seat, and a button on the stem for the manual operation of the valve from without the device While it is being used.

2. A massage device comprising a massage container, a hollow handle connected thereto, a valve between said container and 3f handle, a valve stem in the hollow handle for operating said valve, a cap on the top of the handle, said cap having an aperture therein, a button in said aperture and connected to the end of the stem,.said button 9 having a lower outwardly extending flange lying beneath the face of the cap to prevent the button moving too far out of the aperture,'and a stop r1n on the cap beneath the button to limit the epression of the button.

5 In testimony whereof I have signed my name to this specification.. l
